OVERVIEW

Professional Lenco LDA-2550 Dinse Adapter

The Lenco LDA-2550 (SKU 5472) is a premium welding cable adapter designed to bridge the gap between different generations and sizes of welding equipment. In the industrial welding environment, versatility is key. Often, shops are equipped with heavy-duty welding leads terminated with standard large Dinse connectors (typically 35-50, 50-70, or 70-95 sizes with a ~13mm pin). However, modern portable inverter welders and TIG machines frequently utilize the smaller Dinse 10-25 (approx. 9mm pin) output terminals to save space and weight. The Lenco LDA-2550 solves this compatibility issue instantly, allowing operators to utilize their existing inventory of heavy-duty cables with smaller power sources.

Constructed with the professional tradesperson in mind, this adapter features a solid brass internal body. Brass is chosen for its excellent balance of conductivity and durability, ensuring that the transition between connector sizes does not become a bottleneck for current flow or a source of excessive heat buildup. The male end is precision-machined to fit snugly into any standard Dinse 10-25 machine socket, while the female end accepts any standard large Dinse plug. The connection utilizes the industry-standard cam-lock action; a simple twist secures the adapter to the machine and the cable to the adapter, ensuring a vibration-proof electrical bond.

Safety and durability are paramount in Lenco's design. The adapter is encased in a high-quality black rubber boot. This insulation is not only dielectric to prevent electrical shock but is also formulated to resist the harsh realities of the shop floor, including exposure to oil, grease, solvents, and ozone. Unlike cheaper plastic alternatives, the rubber boot resists cracking and impact damage. This adapter is an essential tool for MRO departments, rental fleets, and mobile welding rigs where equipment interoperability is required. It supports amperages suitable for the 25mm class (typically up to 200-250A), making it perfect for stick and TIG applications.

FAQ

The male end is a Dinse 10-25 size, which has a pin diameter of approximately 9mm (0.355 inches).

The female end accepts large Dinse plugs, commonly referred to as 35-50, 50-70, or 70-95. These all share the same connector geometry with an approximate 13mm pin diameter.

Yes, the adapter is limited by the capacity of the smaller connection side (the 25mm male end). It is generally rated for up to 250 Amps. Do not exceed the duty cycle or amperage rating of the smallest component in your circuit.

The Lenco LDA-2550 features a high-quality rubber insulation boot that is resistant to heat, oil, and impact.

It will fit if your machine uses the small Dinse 10-25 style output terminals. Check your machine's manual or measure the socket diameter (approx 9mm) to confirm.

Yes, the adapter is universal and can be used on either the positive or negative terminal. You will need two adapters if you need to convert both ports.

This product is sold as a single adapter. If you need to adapt both the ground and electrode leads, you should purchase two.
